Benefits of technology

"The invention is a method for improving the quality of sonar images by reducing the data points and creating a two-dimensional image using optical techniques. This helps to create a clearer and more accurate image of the sonar data."

Problems solved by technology

Sonar data is typically returned as a very sparse and very noisy three dimensional matrix.

Embodiment Construction

[0013]It has long been known that data presented in visual form is much better understood by humans than data presented in the form of tables, charts, text, etc. However, even data presented visually as bar graphs, line graphs, maps, or topographic maps requires experience and training to interpret them. Humans can, however, immediately recognize and understand patterns in visual images which would be impossible for even the best and fastest computers to pick out. Much effort has thus been spent in turning data into images.

[0014]In particular, images which are generated from data which are not related to light are difficult to produce. One such type of data is sonar data, wherein a sound waves are sent out from a generator into a volume of fluid, and the reflected sound energy from objects in the ensonified volume is recorded by a multielement detector. The term “ensonified volume” is known to one of skill in the art and is defined herein as being a volume of fluid through which sou...

Abstract

Sonar imaging data is reduced by assigning partially reflective and / or opaque two dimensional areas for each data point to a series of planes. The reflectivity and / or transmission of light from the areas is calculated and used to construct an image.
